Ruddlesden geotechnical

Ruddlesden geotechnical provides ground investigation, geotechnical consultancy and contamination assessment services.

Based in Exeter, but covering the whole of the UK, albeit primarily concentrated in the South West, Ruddlesden geotechnical was formed in 2004.

Ruddlesden geotechnical works on behalf of a wide client base, including local, regional and national housing developers, housing associations, commercial developers, building contractors, structural and civil engineers, architects, building consultants, quantity surveyors, local authorities and private individuals.

Development projects range from single dwellings and extensions to large housing estates, multi-storey flats, offices, industrial units, roads, slopes, schools, hospitals and basements.

The services and projects listed on this web-site provide an indication of those undertaken by Ruddlesden geotechnical, but others are carried out. If your requirement is not readily identifiable on this web-site, please contact us as we may still be able to help you.

    Creative geotechnical photography

    Inspired by her surroundings at RHS Rosemoor, where she was carrying out the ground investigation for a new educational facility, and with one eye on the Ruddlesden geotechnical site photograph of the year competition, Catherine Greed got creative with her site photography recently, framing the dynamic sampling rig within the last of the summer flowers.

    Correct Waste Classification Saves Costs

    Waste classification was undertaken on surplus soil at a residential development site in Exeter. The soil had been purchased and imported to be used as capping beneath road surfaces for the new development. However, the material was later found to be unsuitable for the proposed use. The soil had initially been classified by others as hazardous waste, due to the presence of loose asbestos fibres within the soil matrix. However, following intensive (and representative) sampling of the soil stockpiles, Ruddlesden geotechnical were able to confirm that the soil was non-hazardous waste. Classifying the waste properly, in accordance with Environment Agency guidance, saved the client significant costs, which would have been incurred if the soil were to have been taken to a hazardous waste landfill, as was originally proposed.

    Rotary Borehole Rig Craned-In, in Devon

    Rotary cored boreholes were undertaken as part of a geotechnical investigation for the proposed retaining wall in North Devon. Restricted access meant that the drilling rig had to be craned onto the site. Cores of the rock were recovered and logged by our engineering geologist to confirm the strength, composition, and state and geometry of discontinuities within the bedrock, for use in the design of the proposed retaining wall, which was supporting a public highway and required to facilitate the development. Downhole geophysics was subsequently undertaken to provide further information on the fracture orientation and in-situ condition.
